i have been having problems with my car throwing the belt. quick history: when i first built the motor i installed a dayco belt that was listed wrong in the catalog, ended up being too long and made the knocking/chirping sound and shredded itself to pieces the first time i leaned on it, which destroyed my hood liner and the wires to my iat sensor. with help from this board i switched to the goodyear 4060635 which worked great for a couple months but now it comes off when i lift at like 5k rpm or so. (what i'm picturing is the belt is stretching out under rapid acceleration and the tensioner isnt taking up the slack quick enough when i let off. at least it doesnt come apart like the dayco did, but its frustrating to smoke someone out of a stoplight only to have to pull over and put my belt back on, not to mention the lack of brakes because i'm running hydroboost. is there a measurement like with a spring scale or torque wrench to test the tensioner to verify it before i plop down the huge cash for a new one? also, i am running an a/c bypass which is the same diameter as the stock a/c compressor. i know a lot of people run the s-10 bypass pulley, which is a little larger diameter (like 3/8"). i bought both, should i try the larger pulley to put a little more load on the tensioner? has anyone else had this problem?
